GPU support in quickstart and inquiry about repository maintenance

[adhiiisetiawan]

Issue Description: I started using the quickstart guide in this repository and noticed that it's utilizing the CPU instead of the GPU. I would like to know how to configure it to use GPU acceleration.

Additional Information:

• I have a compatible GPU installed on my system.
• I have installed the necessary GPU drivers and libraries.

Question: Is there any specific configuration or command-line option that needs to be set in order to utilize GPU resources during the quickstart process?

Also, I wanted to inquire about the maintenance status of this repository. Is it still actively maintained and supported?

Thank you.
